This application is a division of our copending application, Serial No. 672,316, filed May 22, 1933.

In the arrangements for the individual electric drive as hitherto applied to winding machines, the motor was always arranged outside of the driving or yarn guiding members. The motor therefore demanded additional room and thereby increased appreciably the floor space required for the often great number of spindle units of a winding machine.

It is true that proposals have already been made to build the motor into the interior of the bobbin carrier (bobbin supporting core) of spinning and twisting machines for rayon, and in some cases the rotary outside armature ofv an electric motor has been developed as a bobbin supporting core. However, this course is only possible in spinning and twisting machines for the manufacture of artificial silk, where the inside diameter of the} bobbin can be made large enough so that it. can-take an electric motor.

The introduction of the motor inside the bobbin or its supporting core presents the drawback that the winding-on speed increases with'the growing bobbin-diameter, a' feature which is permissible in the case of rayon bobbins, because of the comparatively slight difference between the smallest and largest winding-on diameters, the increasing winding-on speed being therefore of no particular importance. In winding machines, however, the diameter of the bobbin tubes is kept comparatively small for the purpose of getting as much yarn as possible into given. outside dimensions for the yarn mass body, thus excluding the possibility of introducing the motor into the bobbin supporting core. But even if it were possible, the difference between the inside and outside diameters of the yarn mass body and the resultant difference between the smallest and greatest yarn speeds would be inadmissible for most kinds of yarn.

The object of the present invention is the elimination of these drawbacks by introducing the motor into the interior of the body driving the body of the yarn guide or into the interior of the thread guide, instead of having it in thebobbin supporting core. It thereby becomes possible to develop the body driving the bobbin, or the yarn guide, or the yarn guide itself into the shell of the rotary outside armature of a rotary motor. The dimensions of these parts can be made correspondingly large without thereby necessitating the slightest increase in the space required for the spindle unit, partricity, compressed air or some other gaseous fluid or liquid.

This application is a division of our co-pending application, Serial No. 672,316, filed May 22, 1933. The several forms of the invention disclosed herein embody an intermediate roller member distinct from the thread guide for imparting rotation to the bobbin.

The invention is illustrated best by the following description of several embodiments thereof, taken in conjunction with the accompanying drawings, wherein Figure 1 is' a sectional view along one of the winding units,

Figure 2 is a front view thereof, with certain parts in section,

Figure 3 is a sectional view of another embodiment of the invention,

Figure 4 is a front view thereof, with certain parts in section,

Figure 5 is a sectional view of another embodiment of the invention,

Figure 6 is a view corresponding to Figure 5 showing the operation of the thread detector upon the breakage of the yarn, and

Figure 7 is a front view corresponding to Figure 5 with certain parts in section.

In the figures showing the several embodiments, 12 is a spindle carying a bobbin 13 to be formed and held in a hinged holder 14. Element 15 is a bracket supporting the essential parts of each spindle unit. All the bearing brackets 15 of a group of units are secured to the angle iron 16 interconnecting the uprights 41. Element 48 is the yarn tensioning device, 49 the detector for the failure of an .end, and 20 the running-off bobbin. The creel pegs holding the running-off bobbins are adjustably secured in known fashion to a shaft which is carried by the angle iron 1'7 connecting the bottom parts of the uprights 41.

In the embodiment shown in Figs. 1 and 2, the package 13 to be formed is driven by. surface friction from a winding drum 1, the shaft of which is rotatably carried in a bearing bracket 15. The winding drum 1 is itself driven over the yarn guiding drum 4, the surface of which has grooves for the to-and-fro movement of the yarn guide 6 sliding on a bar 611. The yarn guiding drum 4 is designed to carry the rotary outside armature 62 of a rotary motor,

the stationary inside field coils 63 of which are preferably mounted on a tube 61 secured to the bearing bracket 15,the current being fed to the motor by the wiring arranged inside the tube 61. The end blocks 59 of the yarn guiding drum 4 can be made to turn on ball bearings 60 threaded on to the stationary tube 61. The operation of this embodiment is clearly visible from Figs. 1 and 2. The motor inside the drum 4 drives the winding drum 1 as well as .the thread guide 6; the winding drum 1, in turn, driving the bobbin 13.

In the embodiment shown in Figs. 3 and 4, the rotary motor is built into the rotary boss of a rotary wing yarn guide 5, known in itself, between end rings 57. Two discs 58 can be arranged at the sides of the rotary wing yarn guide, for the purpose of driving the winding drum or shaft 1 by friction or by gearing.

In the embodiment shown in Figs. -7, the motor is arranged inside the winding drum or shaft 1 in exactly the same manner as described in the embodiment shown in Figs. 1 and 2, and the winding drum or shaft 1 drives the bobbin 13 to be formed as well as the yarn guide roller 4.

The electric circuit for driving the electric motor includes the contacts 50, 51. When the creel bobbin runs empty or the supply fails on account of the yarn breaking, the yarn detector 49 swings to the left as shown in Fig. 6. Its short counter-arm 49a raises the contact 50 and thereby interrupts the feed of the electric current to the motor so that the'drive and the package 13 being formed instantly stop, without requiring the hitherto necessary raising of the package 13 from the driving drum by mechanical means.

Other modifications of the structures disclosed herein may be made without departing from the spirit of the invention as disclosed herein and defined in the accompanying claims.
